No, banning anybody's blog is not a good way of taking care of things. Everybody should be able to say what they want (just make sure not to break a law when you speak things) and he is breaking some laws. For example: extremism, violation of coat of arms. And I don't see why he shouldn't be punished for that, after all he's calling for "justice" then let's justice do the job
Making caricature of Coat of arms is completely anti-patriotic and has nothing to do with current government and I don't see how it would help Russian people to build a strong country
Corruption exposure is good but he's not cooperating with government but goes against it, thus I don't think his target is corruption
And yes, I know that government is corrupted but not every one of them, after all they just people like you and me
His actions are too provocative and it is an open question what they bring more: good or bad, for people in Russia
